WATCH WINDING AND SETTING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 750,619, dated January 26, 1904:.

Application filed June 26, 1903. Serial No. 163,260. (No model.) I

To all whom it may concern.-

Be it known that I, AoHILLE DITEsHEIM, a citizen of the Republic of Switzerland, and a resident of La Chaux-de-Fonds, canton of Neuchatel, Switzerland, have invented certain useful Improvements in Winding and Setting Mechanism, of which the following is a specification.

The winding and setting mechanism which constitutes the object of the present invention 4 is one with double actionthat is to say, it

can be used for so-called negative or indirect setting with divided stem or for or dinary or direct setting with the usual winding-stem.

In the accompanying drawings, Figures 1 and 2 show in side elevation the two positions of a form of execution where said mechanism is used for negative setting, while Fig. 3 shows a form of execution where the same mechanism is used for ordinary or direct setting.

In Figs. 1 and 2 lever A, pivoted on pillarplate P, is provided at g with an extension penetrating into groove G of winding-stem t. The other end of said lever A terminates in two feet. Against the one foot, 0, there is exerted a constant pressure by tail-spring R of setting-bar D, pivoting at (Z, while parts 6 and c of the other foot, M, are to contact with the respective parts B and C of foot 0' belonging to setting-bar D. Said setting-bar ends in projection f of sliding pinion or clutch-sleeve K, and the latter can be eonnected with the gearing of crown Z1, controlling the train of minute-wheels for setting.

Under the end 8 of lever A presses spring S, which latter has the tendency of keeping sliding pinion or clutch K constantly in contact with gearing 7", this position, which is the normal one for setting the hands, being secured by part c of foot M pressing against part C of foot 0, while foot 6 of lever A is secured by tail-spring R of setting-bar D.

If by means of the crown-stem T (of which only the lower part is represented in the drawings) pressure is exerted on winding-stem t, then lever A is acted upon by the latter stem,

and the pressure exerted by part c of foot M on part C of foot 0' being stopped projection f of setting-bar D remounts, rapidly drawing the sliding pinion or clutch-sleeve along and out of the mesh with gear I: and bringing same, on the contrary, in contact with crownwheel N, this being the winding position. (Shown in Fig. 1.) At the same time foot 0 of lever A has placed itself against the inclined plane E of tail-spring R, and part b of foot M has commenced to exert pressure against part B of foot 7'. In this manner there is not only secured the stable position of the parts for winding, but said tail-spring also allows sliding pinion clutch-sleeve K to catch into crown-wheel N. Pin it allows stem tto be fastened immovably in said position for winding.

Spring S has only the purpose to raise projection s of lever A, and consequently also winding-stem If, and if said spring is omitted and stems z. and T are replaced by one single winding-stem T, as shown in Fig. 3, then there will be obtained a direct winding and setting mechanism, whereby the actions of lever A and of setting-bar D are the same as in the first-described case, the stability of the parts being firmly secured in both positions, as described above.

I claim 1. In combination with the crown-wheel N and sliding clutch F and stem, a lever A connected to the stem directly to be positively operated thereby, said lever being pivoted intermediate of its length and havingon its free end feet 0 and c, a setting-bar D having one end engaging the clutch-sleeve and having also a projecting foot I to be engaged by the foot 0 on the lever A, said setting-bar being pivoted intermediate of its length and having a tail-spring R in contact with the foot (2 of the lever A, substantially as described.

2. In combination with the crown-wheel N and sliding clutch F and stem, a lever A connected to the stem directly to be positively operated thereby, said lever being pivoted intermediate of its length and having on its free end feet 0 and e, a setting-bar D having one end engaging the clutch-sleeve and having also a projecting foot 1* to be engaged by the foot 0 on the lever A, said setting-bar being pivoted intermediate of its length and having a tail-spring R in contact With the foot 9 of the lever A, a crown-stem for pressing the stem first mentioned and a spring S pressing up- Wardly under the end of the lever A, substantially as described.

In Witness whereof I have hereunto set my hand in presence of two Witnesses.
